Small-Cap Stock Screen Using Inflows, Three Down Days, and Profitability

Summary

The document proposes a Chinese equity screen combining a reported increase in holdings, three consecutive declining sessions, a market-cap ceiling, and a history of avoiding losses. It then presents a stricter final version with additional return, profitability, and valuation thresholds. The intended idea is to look for smaller profitable companies experiencing short-term weakness alongside increased buying, then filter for business quality and valuation.

The post gives a conceptual explanation of each filter and lists risks: the rules may exclude promising firms, market noise can distort the signals, and the screen may be overly restrictive. It suggests adding financial, technical, and sentiment measures. Sample code is included, but its calculations do not cleanly match the stated rules: the consecutive-decline test, market-cap units, and return thresholds appear inconsistent or incomplete. No backtest results or evidence of profitability are supplied, so the screen should be treated as an unvalidated example rather than an established strategy.

Key ideas

• The proposed screen pairs increased holdings with three declining sessions in smaller companies that have not reported losses.
• The expanded rules add return, profitability, and price-to-earnings filters.
• The post identifies missed opportunities, noise, and excessive selectivity as risks.
• The sample implementation contains apparent mismatches with the described screening criteria.
• No performance evidence is provided to validate the strategy.
